Humans have been striving to decorate their surroundings with various visual elements, such as shapes, textures, and symbols, since ancient times. A lot of times the inspiration for these patterns and textures came from nature, which has always motivated people to create aesthetically pleasing patterns. Geometry assists us to comprehend and reproduce numerous patterns found in nature. Hence, producing geometric patterns has been an integral part of art and ornamental interior design. Exploring a design process for recreating ornamental patterns has led to the development of software for generating Moorish patterns using computer-aided tools. The generated geometric patterns are two-dimensional elements, and could be transformed into three-dimensional objects before they can be used in numerous aspects in interior and architectural design. Thus, combining a two-dimensional pattern with a three-dimensional graphical software, adding extra features and functions to it, provides a powerful tool for artists and designers. The Moorish geometric patterns, renowned for their intricate interlacing and strongly geometric designs, have a long history embedded in multiple cultures. Nevertheless, modern-day computer software has been utilized to incorporate Moorish geometric design into the process of creating interior design- furniture and even in architecture planning and building structures. Computer-aided Moorish geometric design and patterns can influence the manner in which designers and architects create their work. This research traces some of the historical backdrop of Moorish style, the posthumous dynamic of the development of geometric patterns, the advances in PC programming that empower its utilization, and the potential applications of this correlation. The study object was geometric patterns as a form of decoration in architecture and design in the context of geometry and form creating with the purpose of aesthetic search. The study subject was the creation of geometric patterns and the ways possible to make this process faster and more efficient in the work of today’s designer and architects. The study purpose was to investigate the source of making geometric design patterns, in terms of employing them in decorating interior spaces and in architecture in general by a brief exploration in historical samples. By inspecting an example of how PC helped Moorish geometric designs can be used in the process of designing interior places or in architecture planning, this exploration will show how innovation can be utilized to produce works of art and design. The last section concludes by summarizing the main aspects of this work and explaining points for further improvements.
